►MAINTENANCE

• Ensure that the fixing screws, caps and cable glands are
tight.
• Verify that the weight of the cable is supported by the strain
relief mechanism and not by the terminal connections.
• Check the cleanliness of contacts. depress the spring-
loaded ejection ring on two opposite points. The safety
shutter can then be rotated clockwise to inspect contact tips.
Any deposit can be rubbed off with a clean cloth, compressed
air, or a fine emery cloth. Do not file or grind as this would
damage the silver-nickel tips. If necessary, replace damaged
contacts. Do not forget to re-lock the safety shutter after
inspection.
• To replace contacts on Poly-cased DS and DSN, a special key
(P/N° 31-A500-1) is available to remove the retaining clip of
the casing and gain access to the contacts.
• Periodically inspect IP gaskets for wear and tear. Replace as
necessary.
• Regularly check the continuity of the earth circuit by
electric tests.
